Selection exerted by herbivores is a major force driving the evolution of plant defensive characters such as leaf trichomes or secondary metabolites. However, defense expression highly variable among populations and identifying sources this variation remains challenge. Plant are often distributed across broad geographic ranges exposed to different herbivore communities, ranging from generalists (that feed on diverse species) specialists restricted group plants). We studied eight Datura...
• Premise of the study: Wild populations domesticated species constitute a genetic reservoir and are fundamental to evolutionary potential species. papaya (Carica papaya) is rare, short-lived, gap-colonizing, dioecious tree that persists in forest by continuous dispersal. Theoretically, these life-history characteristics render wild highly susceptible habitat fragmentation, with anticipated negative effects on its gene pool. Further, dioecy may cause founder generate local biases sex ratio,...
When plants are introduced into new regions, the absence of their co-evolved natural enemies can result in lower levels attack. As a consequence this reduction enemy pressure, plant performance may increase and selection for resistance to decrease. In present study, we compared leaf damage, size trichome density, as well direction magnitude on between non-native (Spain) native (Mexico) populations Datura stramonium. This species was Spain about five centuries ago constitutes an ideal system...
Plant resistance to herbivores involves physical and chemical plant traits that prevent or diminish damage by herbivores, hence may promote coevolutionary arm-races between interacting species. Although Datura stramonium's concentration of tropane alkaloids is under selection leaf beetles, it not known whether defense reduces seed predation the specialist weevil, Trichobaris soror, if evolving natural selection. We measured infestation T. soror as well plants' two main in 278 D. stramonium...
Theories of plant invasion based on enemy release in a new range assume that selection exerted by specialist herbivores defence traits should be reduced, absent, or even selected against the environment. Here, we measured phenotypic atropine and scopolamine concentration Datura stramonium eight native (Mexico) 14 non-native (Spain) populations. Native populations produced between 20 40 times more alkaloid than (atropine: 2.0171 vs. 0.0458 mg/g; scopolamine: 1.004 0.0488 mg/g, respectively)....
Succulent cacti are remarkable plants with capabilities to withstand long periods of drought. However, their adult success is contingent on the early seedling stages, when highly susceptible environment. To better understand coping strategies in a challenging environment, two developmental aspects (anatomy and morphology) Polaskia chichipe Echinocactus platyacanthus were studied context reaction norms under drought conditions. The morphology was evaluated using landmark based morphometrics...
Defensive traits exhibited by plants vary widely across populations. Heritable phenotypic differentiation is likely to be produced genetic drift and spatially restricted gene flow between However, variable selection exerted herbivores may also give rise differences among To explore what extent these factors promote the among-population of plant resistance 13 populations Datura stramonium , we compared degree ( P ST ) leaf (trichome density, atropine scopolamine concentration) against neutral...
During domestication, lineages diverge phenotypically and genetically from wild relatives, particularly in preferred traits. In addition to evolutionary divergence selected traits, other fitness-related traits that are unselected may change concert. For instance, the selection of chili pepper fruits was not intended structure function leaf epidermis. Leaf stomata trichome densities play a prominent role regulating stomatal conductance resistance herbivores. Here, we assessed whether...
Background: Podostemaceae are extremely susceptible to local extinction by habitat loss. Since ~70 % of the river systems in Mexico show some degree water contamination, it is relevant generate information about seed storage and germination behavior design germplasm conservation strategies ( e.g ., ex situ banks) Mexican podostemads. Hypotheses: Seed decreases as time increases. Further, light quality, temperature collection site influence similarly response both species. Studied species:...
Ensenada wine country, in the State of Baja California, Mexico, accounts for approximately 70–80 % Mexico’s production. Despite its significance, detailed knowledge physical and chemical properties wines remains limited. In this study, we examined nine physicochemical 69 commercial red produced from Tempranillo Cabernet Sauvignon varietals San Vicente, Santo Tomás, Guadalupe valleys. The pH, total acidity, acetic acid, lactic malic polyphenols, glucose/fructose ratio, alcohol content, color...
Wine consumption in Mexico has increased continuously over the last decade. However, domestic wine production is not sufficient to satisfy demand, and foreign producers have been main beneficiaries of growth Mexican market. This highlights need winemakers for scientific evidence technological innovations that can help make better management choices both field winery. paper presents results a bibliometric study aimed investigate contribution academic community literature viticulture oenology...
Damage caused by herbivores reduces plant survival and growth through its effects on mechanisms involved in tolerance to herbivory. Infestation sap-sucking insects negatively affects the expression of metabolites related photosynthesis traits, which an agricultural context can be useful for designing pest management crop breeding programs. The effect infestation vine mealybug Planococcus ficus (Signoret) (Hemiptera: Pseudococcidae) chlorophyll content three varieties Vitis vinifera L....
